It’s a common theme that we hear: Artificial intelligence and robotics are coming for many of the jobs that have traditionally been performed by humans.

But what about the fate of animals?

That prospect was raised recently by David Mantey, a writer for Thomas Publishing, in an article about what’s happening in rice paddy fields. And it involves ducks.

More specifically, aigamo ducks, which are a cross between mallards and domestic fowl. There is a farming method, originating in Japan, that employs these creatures to clear and keep unwanted plants and parasites out of rice paddy fields.

Essentially, it’s an environmentally-friendly practice in which the ducks keep the paddies clear without the need for pesticides. As an ancillary benefit, the ducks’ own waste acts as fertilizer for the rice plants.

The centuries-old practice was revived in Japan the mid-1980s, and has since become a popular natural rice farming method beyond that country, used in places like China, Iran and France.

Broadly speaking, approximately 15 ducks can keep more than a 10,000 sq. ft. area clear of weeds and insects, while also enriching the water with oxygen via stirring up the soil beneath.

It seems like a neat and tidy solution all-around — and one that works based on decades of experience with the farming practice. But as it turns out, it’s something that a robot can accomplish, too (well, maybe not the duck waste bit) — with certain improvements on the original tradition.

A rice paddy robot doing its thing.

While ducks can be “trained” to patrol specific areas of a rice paddy, it isn’t a foolproof proposition. As for the robotic version (which looks more like a white, floating ROOMBA® than it does a duck), it utilizes wi-fi and GPS technology to stir up the soil and keep the bugs at bay.

Reportedly, the robot is more accurate and more consistent in its execution compared to the aigamo ducks.

At the moment, the rice paddy robot is in an experimental phase with beta prototypes patrolling paddies in Yamagata Prefecture in northern Japan — and it’s too soon to know if or when the robot will be deemed ready for commercialization.

But the development goes to show that robots are spreading into some very surprising corners. Indeed, it seems that robotics technology knows no bounds.

2. Employers – especially agricultural operations – have found it nearly impossible to replace the lost workers.

In retrospect, neither development seems particularly surprising. Many immigrant workers, whether they’re here in the United States legally or not, fear the heavy hand of government and will opt to find a more inviting environment than the one in Alabama today. For now at least, that environment is better in nearly all of the other 49 states.

And while the jobs no longer being done by immigrants may now be sought by American citizens – after all, the ~9.9% unemployment rate in Alabama is higher than the overall U.S. rate – the appetite for doing many of these jobs dissipates quickly when people are confronted by the reality of what is required to perform them.

Alicia Caldwell, an Associated Press reporter, spoke last week with some Alabama farmers to find out what has happened since Americans were hired to replace immigrant workers.

“Most show up late, work slower than seasoned farm hands and are ready to call it a day after lunch or by mid-afternoon. Some quit after a single day,” Caldwell reported in her AP article published last week.

As a result, farmers are opting to leave crops in the field rather than harvesting them.

What we have here is a classic Economics 101 lesson. If workers aren’t willing to do the jobs at a labor cost that will enable the products to be sold at a competitive price, the crops won’t be brought to market.

If agricultural operations in the whole world faced the same situation as Alabama farmers, it’s possible that a new labor/price equilibrium could be established. But not only is Alabama competing against other states where immigrant labor continues to be used, it’s also competing against other countries that produce the same crops.

The result? No one is winning. Not the farmers … not the immigrant workers … nor the unemployed Americans who have decided that ramaining unemployed is preferable to working a difficult or unpleasant job.

The Alabama state government is attempting to support the transition away from immigrant workers. A program started recently seeks to pair Alabamians interested in jobs with the state’s farming operations that need replacement labor.

So far, the results of this effort haven’t been encouraging, with only ~260 people registering interest in temporary agricultural jobs.

Out in the field, reporter Caldwell has found ample anecdotal evidence that underscores the disconnect between the “theory” versus “practical reality” of unemployed Americans taking advantage of these new job opportunities:

Tomato farmer Wayne Smith said he has never been able to keep a staff of American workers in his 25 years of farming.

“People in Alabama are not going to do this,” said Smith, who grows about 75 acres of tomatoes in the northeast part of the state. “They’d work one day and then just wouldn’t show up again.”

At this farm, field workers get $2 for every 25-pound box of tomatoes they fill. Skilled pickers can make anywhere from $200 to $300 a day, he said. Unskilled workers make much less.

A crew of four Hispanics can earn about $150 each by picking 250-300 boxes of tomatoes in a day, said Jerry Spencer of Grow Alabama, which purchases and sells locally owned produce. A crew of 25 Americans recently picked 200 boxes – giving them each $24 for the day.

Years ago, an old Russian emigré professor of Slavic history and literature at Vanderbilt University advised us students, “As you grow older and wiser, you’ll come to realize that the great issues of the day can’t be debated in black and white. Because the two sides aren’t black and white; they’re really shades of gray.”

Those words could well be applied to the immigration debate and its socioeconomic consequences. Certainly, one “black and white” issue that should be banished from the discussion is the notion that if all of the jobs done by illegal immigrants were to become available to Americans, our unemployment problem would be magically solved.
